Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
The embodiment of the utility model provides a drainage inspection shaft anti-overflow device, its schematic structure as shown in figure 1, destroy pipe 2, siphon suction pipe 3 including ground water storage tank 1 and the siphon that communicates with ground water storage tank 1. The inspection well comprises an inspection well cover, a shaft, a well chamber, a step and an inspection well bottom. The utility model discloses utilize the siphon principle to stock ground water storage tank 1 with underground inspection shaft overflow water, can remove the erection equipment in advance according to weather department's rainfall forecast, the water is stocked in the water tank, and the effectual water overflow that prevents produces personal loss of property and drowned accident also can install the solenoid valve and prevent to flow on siphon suction pipe 3 if the water has the value in ground water storage tank 1 simultaneously, carries out the reutilization to the water. When the condition of inspection shaft overflow can appear when rainwater flow is great or displacement is great in arbitrary region, can be at this inspection shaft side that has the overflow risk and set up drainage inspection shaft anti-overflow device, can save the unable normal exhaust water body of inspection shaft, prevent the inspection shaft overflow.
Wherein siphon destroys 2 one end and 1 top intercommunication of ground water storage tank, and the other end is visited down to the design liquid level department of inspection shaft, and siphon suction pipe 3 one end communicates with 1 bottom of ground water storage tank, and the other end is visited down to the design liquid level department of inspection shaft. And the variable-frequency vacuum pump 4 is arranged at the top of the ground water storage tank 1, and can carry out vacuum treatment on the ground water storage tank 1 through the variable-frequency vacuum pump 4, so that negative pressure is generated in the ground water storage tank 1. The starting device is arranged at the position of the starting liquid level of the inspection well, can be a liquid level detection device, and outputs a control signal to control the variable-frequency vacuum pump 4 to work when the starting device detects that the water body in the inspection well reaches the same height as the water body. The water in the inspection well flows to the ground water storage tank 1. Wherein the frequency conversion function of frequency conversion vacuum pump 4 adjusts according to the height of the water in the inspection shaft, and when the water height was for being higher than the start-up liquid level, 4 low power mode work of frequency conversion vacuum pump, when the water height reached full load liquid level after, frequency conversion vacuum pump 4 began full load power mode work. The full load level may be a level. Wherein design liquid level department sets up respectively in the inspection shaft with start liquid level department to the design liquid level is less than and starts the liquid level setting, and the design liquid level can be higher than the first distance of predetermineeing of well chamber bottom, and it is higher than the second distance of predetermineeing of design liquid level to start the liquid level. The first and second preset distances may be 0.1m, 0.5m, and 1m, and so on.
Inspection shaft overflow water is deposited in ground water storage tank 1 through the suction pipe, and ground water storage tank 1 closes the vacuum pump after full and stops intaking, and the water tank volume is decided according to on-the-spot overflow water volume, and 2 termination of siphon destroys on the wall of a well of gravity flow design liquid level keep flat position in the inspection shaft, and the other end connects to this water storage tank top, and 1.5% slope is done to 1 bottom of ground water storage tank and is connected to this water storage tank's suction pipe mouth. After the inspection well recovers the gravity flow state, the liquid level in the inspection well drops below the lower port of the siphon damage pipe 2, air enters the siphon damage pipe 2 to enable the air in the ground water storage tank 1 to be communicated with the atmosphere to cause siphon damage, the pressure in the water storage tank is the same as the pressure in the inspection well 1 at the moment, and the liquid in the water storage tank 1 flows through the siphon suction pipe 3 and is automatically discharged into the inspection well under the action of gravity.
When the liquid level reachs the pit shaft bottom in setting up overflow siphon preventing device inspection shaft, the vacuum pump starts, this inspection shaft liquid is through airtight water storage tank internal pressure and atmospheric pressure difference, 3 inflow water storage device through the siphon from this inspection shaft, 4 power reinforcing of frequency conversion vacuum pump when the liquid level surpasses the pit shaft bottom in this inspection shaft, 4 power of frequency conversion vacuum pump are in the peak value when inspection shaft liquid level reachs the well lid bottom, this water storage device closes after being full the vacuum pump and stops intaking, effectively prevent the liquid outflow ground in the inspection shaft, after this inspection shaft liquid level descends to siphon destruction pipe 2 mouths, the air gets into this water storage tank siphon and destroys, liquid backward flow discharges to this inspection shaft.
In one embodiment, a first level sensor 51 is provided inside the surface reservoir 1. The liquid height in the ground water storage tank 1 can be checked through the first liquid level sensor 51, and the liquid height in the ground water storage tank 1 can be displayed through a display device, so that the staff can watch the liquid conveniently.
In one embodiment, the siphon 3 is disposed at one side of the bottom of the water storage tank, and the bottom of the water storage tank is provided with a slope flow groove having a height such that the side where the siphon 3 is disposed is lower than the side where the siphon 3 is not disposed.
In one embodiment, a stainless steel wire screen 01 is arranged at the connection of the siphon break pipe 2 and the siphon suction pipe 3 with the inspection well. Large particle impurities can be prevented from entering through the stainless steel wire filter screen 01
In one embodiment, a second level sensor 52 is disposed within the manhole. The liquid height in the inspection well can be inspected through the second liquid level sensor 52, and the liquid height in the ground water storage tank 1 can be displayed through a display device, so that the liquid height can be conveniently watched by workers. The start-up level is above the design level setting. The inspection well bottom is provided with the slope, and the high one side that is higher than keeping away from the water storage tank of being close to the water storage tank on one side on slope sets up through above mode, can make the silt thing that is attached to the water storage tank bottom flow back to in the inspection well under the drive of fluid and its self gravitational potential energy, avoids appearing the too much condition of silt thing of water storage tank bottom. Wherein be provided with the solenoid valve in siphon suction pipe 3, can control the logical/close of siphon suction pipe 3 through the solenoid valve, can make and deposit water in the water storage tank, make things convenient for the reutilization.
It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
